Genetic variation of onion thrips (Thrips tabaci Lindeman, Thysanoptera Thripidae) populations in Lithuania and their link with host plants

Acta Scientiarum Polonorum: Hortorum Cultus, 2022
Thrips tabaci Lindeman is one of the most important polyphagous horticulture crop pests in Lithuania. The aim of this work was to investigate new approach with the geographic distributions and host plant associations between different mtDNA COI ...

Origin and Distribution of the VRN-A1 Exon 4 and Exon 7 Haplotypes in Domesticated Wheat Species

Agronomy, 2018
The high adaptive potential of modern wheat to a wide range of environmental conditions is determined by genetic changes during domestication. Genetic diversity in VRN1 genes is a key contributor to this adaptability.

Multi‐omic characterization of consensus molecular subtype 1 (CMS1) colorectal cancer with dampened immune response improves precision medicine

Molecular Oncology, EarlyView.
This study highlights the importance of multi‐omic analyses in characterizing colorectal cancers. Indeed, our analysis revealed a rare CMS1 exhibiting dampened immune activation, including reduced PD‐1 expression, moderate CD8+ T‐cell infiltration, and suppressed JAK/STAT pathway.

The mitochondrial DNA HVI and HVII sequences and haplogroup distribution in a population sample from Vietnam

Annals of Human Biology, 2022
Background Mitochondrial DNA (mtDNA) analysis has been used in forensics and requires well-established population databases for statistical interpretations. However, high-quality mtDNA data from Vietnamese population samples have been limited.

The rs10191329 Risk Allele Is Associated With Pronounced Retinal Layer Atrophy in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To investigate whether the rs10191329 risk allele in the DYSF–ZNF638 locus, which is implicated in central nervous system resilience rather than immune‐mediated pathology, is associated with retinal layer thinning, a biomarker of neuroaxonal damage in relapsing multiple sclerosis (RMS). Methods From a prospective observational study,

Genetic Modifiers of Parkinson's Disease: A Case–Control Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the associations of LRRK2 p.G2019S, GBA1 p.N409S, polygenic risk scores (PRS), and APOE E4 on PD penetrance, risk, and symptoms. Methods We conducted a US‐based observational case–control study using data from the 23andMe Inc. and Fox Insight Genetic Substudy (FIGS) databases.

TOMM40 and APOC1 variants differentiate the impacts of the APOE ε4 allele on Alzheimer's disease risk across sexes, ages, and ancestries

Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring
INTRODUCTION The variability in apolipoprotein E (APOE) ε4‐attributed susceptibility to Alzheimer's disease (AD) across ancestries, sexes, and ages may stem from the modulating effects of other genetic variants.

Haplotyping Methods for Pedigrees [PDF]

Human Heredity, 2009
Haplotypes provide valuable information in the study of diseases, complex traits, population histories, and evolutionary genetics. With the dramatic increase in the number of available single nucleotide polymorphism (SNP) markers, haplotype inference (haplotyping) using observed genotype data has become an important component of genetic studies in ...

Single‐Cell RNA Seq in Sydenham Chorea Shows B Cell HLA‐DR/DQ Upregulation and Plasma Cell Proteasomal Activation

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT The pathogenesis of Sydenham chorea remains unclear. We report a 10‐year‐old girl presenting with subacute chorea and mild carditis following Streptococcal throat infection. Single‐cell RNA sequencing on 30,794 peripheral immune cells from the patient and two sex‐matched controls revealed nine immune cell clusters.
